Protecting Our Water

"When you drink the water, remember the spring." - Chinese proverb
I grew up in the shadow of a water tower. On hot summer nights I would climb to the top, sit
with my back against the tank and wait for the cooling breeze that would arrive just after
midnight. Then someone discovered aerosol spray paint. A creative lover painted a giant heart
emblazoned with his and his sweetheart's initials on my water tower. As a result, the waterworks
installed a barbed-wire climbing barrier around the base, blocking access to the ladder and
ending my nightly ascent.

Those were the simpler days after the Great War, which, we were told, had brought peace to the
world. On the other side of the earth, seeds of another war were sprouting in the sands of the
Middle East. We saw the bitter harvest a half century later on the morning of September 11,
2001.

New Threat, New Legislation
As America recovered from the shock of the attacks, Congress enacted a flurry of acts with the
intent of protecting our infrastructure from terrorists. Legislation affects nearly every
infrastructure of our daily lives: transportation, food, energy and water. Among the reams of
legislative paper is Public Law 107-188, the Public Health Security and Bioterrorism
Preparedness and Response Act of 2002. This act provides guidelines and grants to protect
America's food, drug and water supply.

The President's National Strategy for Homeland Security delegated the protection of the nation's
water supply to the U.S. Environmental Protection Agency. Because the EPA already manages
programs to ensure water quality, adding responsibility for security management was a natural
fit. Among the EPA's goals is "...assessing and reducing vulnerabilities and strengthening
detection and response capabilities for critical infrastructures."

The EPA maintains a Water Security Web site (www.epa.gov/safewater/security) with links to
volumes of information, including the Water and Wastewater Security Product Guide. The guide
organizes products by three concepts: detect, delay and respond. Product descriptions are
generic, though some vendors' products are listed as examples.

Planning Resources
Large cities have long considered security a requirement for their water treatment and
distribution facilities. Their security plans were designed to combat equipment theft and
vandalism rather than to deter bioterrorism. Metropolitan water plants use fence protection
extensively, and some have advanced intrusion detection devices such as CCTV, fence sensors
and buried cable sensors. However, the majority rely on physical security products such as locks,
barbed wire and ladder access controls to deter intruders. The Homeland Security Act authorized
grants to cities to purchase additional security systems for water utilities.

The EPA's Drinking Water Academy, in collaboration with the Association of Drinking Water
Administrators (ASDWA) and the National Rural Water Association (NRWA), developed the
Security Vulnerability Self-Assessment Guide for small drinking-water systems serving
populations between 3,300 and 10,000. The assessment is comprehensive and could serve as a
guide to other utilities and processing plants as well. In addition to asking administrators to list
the facility's physical plant, this assessment questions critical security-related assets such as
fences, lighting, locking hardware, access control and intrusion detection and response.

Budgetary Complaints
A frequent complaint from state and city officials is that the Department of Homeland Security
issues initiatives and mandates, but the funds provided to meet its goals are inadequate. At first
glance, it would appear that the DHS 2004 counterterrorism grants would more than cover the
cost of increased security expenses. However, of the $2.2 billion in grants, only one fourth ($497
million) is earmarked for prevention and deterrence.

Further, the total grant is shared by 50 states, five territories, and many cities and towns. The
2004 Urban Area Security Initiative (UASI) allocations for cities total $671 million and are
distributed by infrastructure threat rather than by population alone. For example, the City of San
Francisco ranks 14th in population but is fifth on the list of DHS grants due to critical
infrastructure.

The 50 largest U.S. cities receive the highest grant funds, and the remainder is divided among
thousands of small towns and rural areas. Terrorists have shown that they target high-profile
institutions. However, as these targets become highly protected, the probability of attacks on soft
targets increases.

At the time of the 9/11 attacks, many rural and small-town water treatment plants lacked the
most basic security assets, such as perimeter fencing. Faced with budget cuts and the smallest
portion of DHS grants, smaller utilities struggle to meet the requirements of the EPA's
Homeland Security Plan. Advanced perimeter intrusion detection technologies such as buried
sensor cable and seismic and microwave fence detectors would be ideal for many sites.
Regretfully, the cost to retrofit existing sites with these technologies is beyond the budgets of
smaller water districts. Several manufacturers have broadened their security products to meet the
demands of both large and small utilities.

Key control is of utmost importance in maintaining a secure facility. IR's Schlage Lock
Division's Primus(r) cylinders are restricted and offer high pick resistance. Schlage offers
network and offline electronic locks that have time controls and event logging. These locks will
work with most existing magstripe and proximity card technologies. In the event a card is lost or
stolen, the locks can be quickly reprogrammed with a hand-held PDA.

Climbing Deterrents and IDS
Security professionals share a great concern about intruders climbing on structures and tanks.
Since the attacks of 9/11, utilities' primary focus has been on measures to prevent terrorism.
However, intruders that gain access to utilities pose a threat to the property and themselves. An
intruder who is injured on a hazard that is not properly protected can sue the utility regardless of
his or her intent. This writer served as an expert defense witness on a case in which intruders
who had no legitimate business being in a facility, and in fact were actually vandalizing the
property, were injured. They claimed the hazards within the perimeter were not properly
protected and won a settlement.

Proper climbing protection includes blocking access to ladders and service catwalks. RB
Industries of Greensboro, NC, makes a locking ladder cover that is an eight-foot-high by three-
foot-wide aluminum shroud that blocks access to the bottom of a tower ladder. Manufacturers of
similar products include Carbis Inc., Serrmi Products Inc. and Brock Manufacturing.
In 1993, Protection Technologies Inc. of Reno, NV, released its Pyramid series dual-technology
stereo Doppler intrusion detector for outdoor use. The product is ideal for spot detection and for
use with other perimeter intrusion detection technologies. Recently ProTech developed a
variation on this product, the Pyramid LT. Using dual-channel microwave and passive infrared
technology, the new sensor detects one-way motion in the outdoor environment. This makes the
product ideal for detecting intruders climbing ladders or towers. When placed at the top of a
structure and aimed downward, the detector will alarm if a person or object moves more than 40
inches toward the sensor.

In tests and field conditions, the detector remains stable in a driving rainstorm because water and
airborne debris moves across or away from the detection field. Likewise, vehicular and
pedestrian traffic beneath the sensor do not cause nuisance alarms. Installers can field configure
the LT to alarm when someone is moving away from the detector or approaching and receding
from the sensor, making it ideal for catwalks and emergency escape ladders.
The output of the Pyramid LT is a dry contact transfer that can be connected to any peripheral
device such as lighting, CCTV or a wireless alarm transmitter. It was quickly adopted by several
water utilities in the United States because it offers reliable protection against climbing.
The applications for the Pyramid LT are not limited to water utilities. It also works for for high-
tension transmission line towers, microwave telecommunication and grain storage structures.
Protection Technologies builds the sensor into an explosion-proof enclosure for use in hazardous
and explosive environments.

Remember the Spring
A Chinese proverb says, "When you drink the water, remember the spring." The Department of
Homeland Security has heeded this advice. Protecting the nation's water supply from terrorism is
a high priority of the DHS. Water, food and fuel production facilities rely on physical security,
electronic intrusion detection and response systems to reduce the threat of vandalism, malicious
contamination and potential injury litigation.

The DHS provides grants to protect water, food and fuel facilities. However, the funds are
allocated to vast infrastructure. Utilities must choose protective measures within tight budgets.
The EPA's Water and Wastewater Security Products Guide is a great place to begin the search
for the right products to remember your spring.
